We look at the division of 862401 by 27 
The aim is to understand the frequency of 27 in 862401.

Step 1:
The number 27 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 27

Moving on to step 2:
When dividing 86 by 27, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 5 after subtracting 81 from 86.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 27

On to step 3:
52 divided by 27 is 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 27 from 52 leaves us with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 27

Step 4:
When dividing 254 by 27, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 319.0
Subtract 243 from 254 to get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 27

Let's proceed to step 5:
110 divided by 27 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 3194.0
The remainder is 2 after subtracting 108 from 110.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 27

Step 6:
21 divided by 27 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 31940.0
If we subtract 0 from 21, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
The number 27 fits into 210 7 times, leaving a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 31940.7
If we take 189 away from 210, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
27 goes into 210 7 times with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 31940.77
If we subtract 189 from 210, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 31940.77 with a remainder of 0.021.
